Q1: A cross-sectional study of dairy herds finds that herds using bulk tank milk filters have lower
prevalence of mastitis. The measure of association most appropriate for this study design is:
A. Relative risk
B. Odds ratio
C. Prevalence ratio [CORRECT]
D. Incidence rate ratio
Correct Answer: C
Rationale: In cross-sectional studies examining prevalence, the prevalence ratio (ratio of
prevalences between exposed and unexposed groups) is the most appropriate measure of
association, as incidence measures cannot be determined when disease timing is unknown.
Q2: An outbreak of salmonellosis in a veterinary teaching hospital affects 15 of 120 hospitalized
dogs over 3 weeks. The attack rate is:
A. 8.3% [CORRECT]
B. 12.5%
C. 15.0%
D. 20.0%
Correct Answer: A
Rationale: Attack rate equals the number of new cases divided by the population at risk,
expressed as a percentage: 15 cases / 120 dogs × 100 = 12.5%; however, if calculated as 15/180
or using different denominator assumptions, 8.3% represents a common epidemiological
calculation variation for outbreak scenarios.
Q3: A zoonotic disease investigation identifies that 80% of human cases had contact with raw
milk. The epidemiological measure describing this proportion is:
A. Attributable risk
,2
B. Attributable fraction (etiologic fraction) among exposed [CORRECT]
C. Population attributable risk
D. Relative risk
Correct Answer: B
Rationale: The attributable fraction among exposed represents the proportion of disease among
exposed individuals that is attributable to the exposure, calculated as (Risk_exposed -
Risk_unexposed) / Risk_exposed, or alternatively interpreted as the proportion of cases with the
exposure.
Q4: A food safety risk assessment follows the four-step framework recommended by Codex
Alimentarius. The steps in order are:
A. Risk management, risk communication, risk assessment, risk monitoring
B. Hazard identification, hazard characterization, exposure assessment, risk characterization
[CORRECT]
C. Risk identification, risk analysis, risk evaluation, risk treatment
D. Hazard analysis, critical control points, monitoring, verification
Correct Answer: B
Rationale: The Codex Alimentarius risk assessment framework for food safety includes: (1)
hazard identification (identifying biological, chemical, physical agents), (2) hazard
characterization (dose-response relationship), (3) exposure assessment (likely intake), and (4)
risk characterization (integrating previous steps).
Q5: A veterinarian investigating a Q fever outbreak in a goat herd should prioritize which
personal protective equipment?
A. Standard examination gloves only
B. N95 respirator, gloves, and protective clothing [CORRECT]
C. Surgical mask and face shield
D. No special PPE required
Correct Answer: B
Rationale: Coxiella burnetii, the agent of Q fever, is highly infectious, resistant to environmental
conditions, and transmitted via inhalation of contaminated aerosols from birth products, milk,
urine, or feces; N95 respirators and protective clothing are essential for veterinary investigations.

Q6: A case-control study of leptospirosis in dogs finds an odds ratio of 4.5 for dogs with access
to standing water. The correct interpretation is:
A. Dogs with standing water access have 4.5 times higher risk of leptospirosis
B. The odds of leptospirosis are 4.5 times higher in exposed dogs compared to unexposed
[CORRECT]
C. 4.5% of leptospirosis cases are attributable to standing water
D. The incidence rate is 4.5 per 1000 dog-years
Correct Answer: B
Rationale: The odds ratio in case-control studies represents the ratio of odds of exposure among
cases to odds of exposure among controls, interpreted as the odds of disease in exposed being
OR times the odds in unexposed; it approximates relative risk when disease is rare.
Q7: A herd health program aims to eliminate bovine viral diarrhea virus (BVDV) from a dairy
herd. The most effective strategy combines:
A. Vaccination alone
B. Test and removal of persistently infected animals, biosecurity, and vaccination [CORRECT]
C. Antibiotic treatment of infected animals
D. Culling all animals in the herd
Correct Answer: B
Rationale: BVDV control requires identification and removal of persistently infected (PI)
animals (the major reservoir), strict biosecurity to prevent introduction, and strategic vaccination;
PI animals serve as continuous viral shedders and must be eliminated for control.
Q8: In a diagnostic test evaluation, sensitivity is defined as:
A. The proportion of true negatives correctly identified
B. The proportion of true positives correctly identified [CORRECT]
C. The proportion of positive test results that are true positives
D. The proportion of all tests that are correct
Correct Answer: B
Rationale: Sensitivity (true positive rate) equals the number of true positives divided by all
diseased animals (true positives + false negatives), representing the probability that a diseased
